Artificial intelligence for direct-to-physician reporting of ambulatory electrocardiography
Why the study?
Ambulatory ECG technology generates vast amounts of data currently requiring human technician interpretation, prompting the evaluation of an AI algorithm for direct-to-physician reporting.
Does an ensemble AI model (DeepRhythmAI) improve the identification of critical arrhythmias in ambulatory ECG recordings compared to certified ECG technicians?
Population
14,606 individual ambulatory ECG recordings
Comparison
DeepRhythmAI model vs 167 certified ECG technicians
Design
Comparative diagnostic accuracy study
Key result
DeepRhythmAI detected critical arrhythmias with 98.6% sensitivity versus 80.3% for technicians, reducing false-negatives by over 10-fold but increasing false-positives.

May support AI triage of ambulatory ECGs despite more false positives; leaves open outcome impact in prospective use.
Does an ensemble AI model (DeepRhythmAI) improve the identification of critical arrhythmias in ambulatory ECG recordings compared to certified ECG technicians?
The DeepRhythmAI model demonstrates superior sensitivity and significantly reduces false-negative critical arrhythmia diagnoses compared to human technicians, though with a modest increase in false positives.
Johnson et al. (2025) studied this question. DeepRhythmAI detected critical arrhythmias with 98.6% sensitivity versus 80.3% for technicians, reducing false-negatives by over 10-fold but increasing false-positives.
